preparation example Construction

[0019] The invention also discloses a preparation method of an aqueous metal cleaning agent containing nano-silver, comprising the following steps:

[0020] a. The selection of nano-silver is to select an aqueous solution of nano-silver with an average particle size of 10-100nm and a total silver content of 2000-8000ppm.

[0021] b. Stir and mix the nano-silver solution, inorganic base, emulsifier, deionized water and other functional additives according to the set weight parts until they become transparent.

[0022] The invention also discloses a method of using a water-based metal cleaning agent containing nano-silver. The cleaning agent is diluted with water by a volume ratio of 1:5-200 times, and is used for ultrasonic cleaning, spray cleaning, and manual cleaning of light to heavy oil stains on industrial metals. Wipe cleaning and other processes.

[0023] In addition, the aqueous cleaning solution containing nano-silver is diluted with water at a volume ratio of 1:30, w...

Abstract

The invention relates to aqueous metal cleaner containing nano-silver. The aqueous metal cleaner containing nano-silver is characterized by comprising, by weight, 0.5-10 parts of aqueous nano-silver solution, 1-30 parts of inorganic base mixture, 1-30 parts of emulsifier mixture, 0-20 parts of additives with other functions and the balance 100 parts of deionized water. The aqueous metal cleaner containing nano-silver is high in decontamination ability, long in service life, friendly to the human body, non-hazardous, free of stimulation and corrosion and capable of effectively guaranteeing the health and safety of operators and not polluting the surroundings. Meanwhile, rancidity and deterioration of work liquid are avoided, and the work liquid can be circularly added and used and does not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of industrial metal cleaning, in particular to an aqueous metal cleaning agent containing nano-silver and its preparation method and use method. Background technique [0002] Water-soluble metal cleaning agents have good cleaning properties and water dilution ratios, are easy to separate and return to disposal, and have a long service life. [0003] In order to reduce the cost and prolong the service life of the water-based metal cleaning agent, it is necessary to prevent the water-based metal cleaning agent from spoiling, and to add fungicide components to it. At present, the commonly used fungicides are organic fungicides such as morpholine and triazine. Such organic fungicides are generally highly corrosive, have a pungent smell, and will inevitably volatilize into the air during use and contact the operator's skin, which may cause the operator to vomit, skin allergies or even faint; have adverse effects...
